Objective To evaluate the biocompatibility,immunology and physiologic features of encapsulated Newborn Porcine Islets(NPI) in the liver of the recipient dogs with type I diabetes.Methods Type I diabetic dogs were perfused with 400 000-600 000 encapsulated NPI(group A,n = 15)or unencapsulated NPI(group B,n = 15)through the hepatic artery without immunosuppressive treatment.Liver function and CD4/CD8 in the recipients were measured before and after the transplantation.The livers from all NPI recipient dogs were analyzed by histopathology 6 months after transplantation(Tx).Results Insulin dose administrated to group A was reduced gradually within one week after Tx,from 22 u before Tx to 5 u after Tx,exogenous insulin required for group B was decreased from 24 u to 10 u.However,2 to 3 weeks after Tx,the insulin dose given to group B returned to the original level before Tx.In contrast,the amount of insulin administrated to group A was continually reduced to 8 u.Moreover,CD4+ cells in the blood of group B recipients were higher than that before Tx,whereas no significant alteration of CD4+ cells and CD8+ cells in the blood of group A after Tx.All NPI recipient dogs demonstrated a normal function and structure of the liver after Tx.Conclusion Microcapsulated NPI has a good biocompatibility in recipients livers providing prolong-ation of xenograft survival,and correcting the hyperglycemia of diabetic canines.(J Intervent Radiol,2006,15: 607-610)

As a common disease in clinical, the treatment of lumbar disc herniation (LDH) focused on local intervertebral disc, such as surgery and other interventional therapy treatment, but postoperative complications and recurrence rate has been a difficult problem in the field of profession. With the development of spine biomechanics and anatomy, researches on lumbar herniation also increased. Researchers discovered that the incidence and prognosis of LDH were inseparable with local muscle and soft tissue. As the deep paraspinal muscles, multifidus muscle plays an important role to make lumbar stability. Its abnormal function could reduce the stable of lumbar spine, and the chronic lumbar disease could also lead to multifidus muscle atrophy.

Objective To quantify the white matter hyperintensity (WMH) with serial MRI in elderly people with cerebrovascular disease, and to evaluate the risk factors that may have impact on their progression.Methods One hundred and thirty-eight patients with cerebrovascular disease underwent twice MRI scans with a 1.5T MR scanner at least one year apart (mean = 13.8 months). The clinical data of all patients, including age, gender, systolic blood pressure, blood glucose level, serum lipid level, alcohol consumption and smoking were recorded at baseline, as well as the historical informations concerning hypertension, diabetes mellitus and hypercholesterolemia. Besides, the overall severity of cognitive impairment and neural deficit of patients were rated by Mini-Mental State Examination (MMSE) and the National Institute of Health Stroke Scale (NIH). MRI measures included volume of gray matter infarction, volume of white matter infarction, and baseline volume of WMH. The volumetric changes of WMH between the twice scans were assessed using a semi-automated software. The influence of risk factors on changes of WMH volume was analyzed. Correlation coefficients were calculated between clinical scales and the change of WMH volume. Results The Baseline WMH volume was(13155?18782) mm3, and the volumetric change of WMH was(7687?9079) mm3. Multiple regression analyses revealed that the occurrence of infarction in cortex and in white matter was significantly associated with the volumetric change of WMH, as well as the baseline WMH volume. The volumetric changes of WMH were related to MMSE and NIH score (r=-0.266,P=0.002; r=0.257,P=0.002). The total infarcted volumes were associated with the volumetric change of WMH (r=0.416,P

OBJECTIVETo study therapeutic effects between hook plate fixation and modified Weaver-Dunn surgery for the treatment of acromioclavicular joint dislocation.

METHODSForty patients with fresh acromioclavicular joint dislocations of type III according to Rockwood classification were reviewed. All the patients were divided into two groups: hook plate fixation group and modified surgery group. There were 20 patients in hook plate fixation group, including 13 males and 7 females, with an average age of (37.45 +/- 14.29) years old; 12 patients had injuries in the left and 8 patients had injuries in the right; preoperative Constant-Murley score was 40.75 +/- 10.40. And there were 20 patients in modified surgery group,including 11 males and 9 females, with an average age of (41.65 +/- 14.83) years old; 11 patients had injuries in the left and 9 patients had injuries in the right; preoperative Constant-Murley score was 42.75 +/- 8.18. The Lazzcano standard, Constant-Murley score and imaging changes were used to evaluate shoulder joint function before and after surgery.

RESULTSAll the patients were followed up,and the duration ranged from 7 to 32 months,with an average of 24 months. According to Lazzcano evaluation, 16 patients got an excellent result,3 good and 1 poor in modified surgery group with no re-dislocation, and 1 patient had pain more than middle degree; while in hook plate fixation group, 9 patients got an excellent result, 7 good and 4 poor, 1 patient had re-dislocation, and 3 patients got pain more than middle degree. The therapeutic effects of modified surgery group were better than those of hook plate fixation group. Constant-Murley scores:preoperative 42.75 +/- 8.18 vs 93.40 +/- 4.04 at the latest follow-up in modified surgery group; preoperative 40.75 +/- 10.40 vs postoperative 88.40 +/- 4.81 and 92.05 +/- 4.49 at the latest follow-up in hook plate fixation group. The postoperative scores all improved compared to preoperative scores in two groups. And there was no statistical difference of scores at the latest follow-up between two groups.

CONCLUSIONThe surgery of allograft tendon transplantation combined with anchor fixation to strengthen coracoclavicular ligament, as well as part transposition of acromiocoracoid ligament and resection at the distal part of clavicle may got safety fixation and less postoperative complications compared with hook plate internal fixation.

OBJECTIVETo study clinical effects of short-segment fixation and injured vertebra bone grafting through injured pedicle for the treatment of thoracolumbar burst fractures under MAST Quadrant retractor via a paraspinal muscle approach.

METHODSThe data of 42 patients with thoracolumbar burst fractures treated from June 2009 to September 2012 were reviewed. There were 19 males and 23 females, with an average age of (55.2±11.9) years old. The mean injury time was (5.8±4.3) days. Fracture segments included T10 in 3 cases, T11 in 6 cases, T12 in 13 cases, L1 in 9 cases, L2 in 7 cases, and L3 in 4 cases. According to Denis classification, 9 patients were type A, 21 patients were type B, 5 patiens were type C, 5 patients were type D, and 2 patients were type E. All the patients were treated with short-segment pedicle screw-rod system fixation under MAST Quadrant via the paraspinal muscle approach. The operative time, blood loss, complications and the height of vertebra, kyphosis Cobb angle, VAS scores, JOA scores were measured before and after treatment.

RESULTSAfter treatment, the vertebral height and kyphosis Cobb angle were restored. Compared with preoperative results, postoperative vertebral height and kyphosis Cobb angle, VAS scores and JOA scores were all improved. But there was no statistically significance in vertebral height, kyphosis Cobb angle between postoperative at 1 week and 1 year.

CONCLUSIONInternal fixation combined with injured vertebra bone grafting through the injured pedicle for the treatment of thoracolumbar burst fractures via the paraspinal intermuscular approach under MAST Quadrant is a safe, minimally invasive, effective and satisfactory method.
